By "same settings" with the wireless system, I did not describe the mode of the 580EX IIs.
By wireless, I did mean the ST-E2 device but the built-in infrared system that works in conjunction with ETTL II.
I understand (perhaps incorrectly) that the off-camera 580EX has to be in slave mode to work with the Flex system
I bought the PW devices expecting straightforward ease of use, and found anything but.
The manual begins with a description of every update to the software, instead of with a plain-language guide beginning with basics and necessities.
The system appears to go to sleep even though I set the flash custom function to disable sleep action. At times, I have to turn off the camera and turn in it back on to get the system to work.
When I have a subject sitting on the stool in my small studio, I want my flash units to trigger every time without the concern for unreliable triggering which the PW devices introduce.
I even bought the AC3 hoping it would reduce the process to the advertised and ballyhooed simplicity, and it did not perform as hoped.
As a technically trained and inclined individual, I certainly know and understand the role of the operator as the possible origin of error.
I did take the time to download and install the latest PW updates to each device. I have the unfriendly manual. I suppose I must knuckle down to learn this flash control system for my eventual location flash activity. Meanwhile, I find myself rather disappointed with the apparent flakiness of the PW.
